Too/ll whom it may concern.- Y

Bei't known thatLAnrHEUsBUTLE MARsH, a citizen of the United States,,anda resident of Whitman, countyof Sumner, and-State of Kansas, haveinvented certain new and use ful Improvements in Cultivators, of whichthe following is a specification, reference being bad totheaccompanyingdrawings, forming a part thereof, in which similarletters of refer enceindicate corresponding parts. This inventionrelates to that class of cultivators in which concave disks are usedtoloosen and stir the soil; j v Many ofthe disk cultivators heretofore inuse ould inspite, of. the utmost care when the corn or other plant to becultivated. had grown to beeig'ht, Ql Illl16 inches high cut down theplant. It was alwaysheretofore very difficult, if not quitedmpossible;to stir and loosenfthe ridges betweene rows of corn to the 'bottomwithanyof the disk cul-. tivators in use. These disadvantages, among others,greatly hindered an iron d ered d ifficult the cultivation of corn ands'uclrother p'lai 1 ts as were planted in rows End whic" had. attainedthe height of eightornine inches with disi; cultivators. It istp'obviate these diifi culties that my presentinvention has been devised.

Fall;

The natureof the invention-consists in the combination and arrangementof the divers parts of thesaid cultivator, as will be more fullyhereinafter described,and subsequently pointed out in the claims.

In the accompanyingv drawings, forming part of thisspecificatiomflhigure lis a top plan view of my newly-inventedcultivator. Fig. 2 is a sectional view in, elevation, taken on the lineat w of Fig. 1. Fig. 3 is a rear end detail view of the shield formingpart of my A designatesailinrizontal beam which is to be ofasuita-hleelength relative to the distance hetweemtnvo-altiernateerowsof corn.

O designates the tongue, and B the drivers Thiseseat is attached by Lhespring H to the horizontal beam A. In this beam A are formed twobearings, (designated by a.) In these hearings are set the metallicbushes a. D and E designate metallic plates which are formed withbearings to register with the bearings in the same beam. These platesare Serial No. 107,908. (.No model.)

held in proper posit-ionby the gii.y.--i'ods d and e. F G designateupright posts which are pivoted in the hearings in said beam and Thetops fastened the leversM and M.

brackets fastened on .the said beam. On

these are pivoted the levers Oand 0'. These levers areconnected to thelevers M and M by the rods N and N, so thatby moving the levers 1 O- andO the posts Fmay be turned in their bearings. The shafts F are journaiedthrough the-enlargements F G of the posts PG and held against lateralmovement by means of collars f g and nuts f 'g. The posts F G are eachformed With'a'loop .0 through which pass the eyes csof 'thefBrace-rodsa, steadilyholding said posts in i' pright position. On the shafts F arerevolubiy mbunted the cultivator-disks L L and- K K, which are heldagainst lateral movement bgnthe collars f g and nutsf 9 tion here giventhere are two of these shafts used. These shafts with theirgangsof disksare arranged so that they will work one on each side of a row of plants.x

Itis intended only to use this machine when the plants are comparativelysmall and that In the example of my inven shown, and on each areillustrated four disks, Any suitable andconvenient number may be' i wthe machine shall straddle the row,1 a A woraing on both sides of it.This necessitates somemeans to prevent the clods from falling on thesmall plants and injuring them. For this purpose I provide the shield 1,formed with the wingsl and the integral arched brace 1 This is made ofsuch a size that while the cultivator is in operation one wing may be oneach side of the row, moving'with the machine. It is detachably andpivo'taliy trated. The chain Q is connected to the arched brace Piandarranged to raise up and let down the shield, so as to adjust its heightas may be required, the free end of the said chain passing through thefork R, which extends rearwardly from the beam A, whereby any suitablelink of the chain may below-'- braced to hold the shield in requiredposition.

This cultivator when in use straddles the row it is cultivating, andwhile the disks stir up and loosen the ridges between thearows connectedto the tongueC by. a bolt 2, as illusthe shield moving along with thecultivator with its wings'one on each side of the row prevents any clodsfrom falling upon the tender plants to damage them. It will then befound that on account of the protection of the shield on the side andthe proper length of the beam on the other side the disks will not cutdown the plants and that the soil will be more deeply and thoroughlystirred and loosened than by any implement of this class now in commonuse. Aside from what is herein set forth this cultivator is used in -thecommon and well-known way.

I,do not strictly confine myself to the con-- i am entitled to slightstructural variations.

Having now fully describfd what my invention is and how the same isused, I claim as new and desire to secure by Letters Patent 1. In acultivator, the combination with a horizontal beam, formed with bearingsfor the accommodation of upright posts, and means of tractionfor saidcultivator; of-upright posts, pivoted in said bearir' s, shafts belowand parallel, to said horizontal beam, carried by said posts, andarranged to turn with them, plates formed with perforations, of propersize to fit upon the upper ends of said posts, and held in position overthe top of said horizontal beam, guy-rods holding said plates inposition, means for turning said posts, and a plurality ofcultivating-disks on said shafts, arranged to stir and loosen the soilon both sides of a row of plants simultaneously. v

2.' In a cultivator, the combination with a horizontal beam, formed withbearings for upright posts, metallic bushes in said bearings, metallicplat-es formed'with bearings registering with the hearings in said beam,and held in'place above said beam, guy-bars so holding said plates inposition, and means of traction for said cultivator; of upright postspivoted in said bearings, in said beam, and plates,

shafts, carried by said posts, below and par 'allel to said horizontalbeam, a plurality of cultivating-disks on said shafts and means forturning said upright posts.

3. In a cultivator, the combination with a horizontal beam, formed withbearings for upright posts, plates also formed with bearings registeringwith the bearingsin said bean1,guyrods holding said plates in positionabove said beam, and means of traction for said cultivator, of uprightposts, pivoted in said bearings in'said beam and plates, shafts carriedby said posts, under and parallel to said tal beam, a pluralityof'cnltivating-disks on said shafts, horizontal levers attached to thetops of said posts, brackets on said horizontal beam,levers pivotallymounted on said brackets, and bars connecting said pivoted levers andsaid horizontal levers, and said bars and said levers afiording facilityfor turning said posts. g

4. In a cultivator, the combination with a horizontal beam, formed withbearings for upright posts, plates formed with bearings regis-,

tering with the hearings in said beam, guyrods holding said plates inposition above said beam, and means of traction for said cultivator, ofupright posts, pivoted in said bearings, means for turning said posts,shafts carried by said posts, under and parallel to said horizontalbeams, a plurality of cultivatingdisks on each of said shafts,and thegangs of disks so arranged that they will cultivate rows of plants, byloosening and stirring the soil on both sides of the row at once, andshields formed with two wings, attached to said cultivator and arrangedto act as clodfenders, by moving with' one wing 'on'each side of saidrow, and simultaneously protecting both sides of said row of plants.

5. In a cultivator, the combination with a horizontal beam formed .withbearings for upright posts, plates also formed with bearings registeringwith the bearings in said beam, guy-rods holding said plates inposition,above said beam, and means of traction for said cultivator; ofposts pivoted in said bearings and 'means for turning said posts, shaftscarried by said posts, below and parallel to said horizontal beam, aplurality of cultivating disks on each of said shafts arranged to loosenand stir the soil on both sides of a row of plants at once, a shieldformed with two wings, and arranged by i'nterposing. its wings betweenthe said gangs of disks, and said plants, to protect said plants on bothsides at once, while being so cultivated, means for detachably attachingsaid shield to 'said cultivator, and means for ad justiug the same whenso attached thereto.

In testimony that I claim the foregoing as my invention I have signed myname, in pres;

ence of two witnesses, this 16th day of 'April, 1902.
